If you are unfamiliar with the App Store, first of all, congratulations. This is pretty brazen gangster behavior — gangster tech regulation, to be more precise. And Twitter was arguably in violation of App Store guidelines before Musk bought it, as Tumblr CEO Matt Mullenweg noted. Despite all these flagrant violations of App Store policies, Apple has not removed Grok or X from the store. So in practice, if Apple is preferencing its own apps in the App Store editorial sections, that may be an antitrust violation.
